Automotive Dashboard Air Vent Trim Injection Molding Part

As a key aesthetic cover component in the central control area of the automotive cockpit, this elongated component integrates the functions of an air conditioning vent grille, decorative bezel, and internal mounting brackets. Its design features large-area continuous surface transitions combined with sharply defined geometric facets, enhancing the visual texture of the interior while achieving a seamless interface with the main dashboard body.

This type of part demands extremely high dimensional stability in injection molding, requiring strict control over warpage in long-span structures and sink marks in thin-walled areas. In particular, the mating tolerances between the vent blade slots and surrounding assembly positions directly impact the gap and flushness performance during final assembly. Surfaces typically undergo leather grain texturing or high-gloss finishing, with zero tolerance for aesthetic defects. Optimized mold flow analysis and holding pressure strategies are employed to ensure concealed weld lines and consistent gloss levels.

Supported by an IATF 16949 quality management system, our factory is equipped with Haitian injection molding machines ranging from 86 to 1600 tons and Makino precision machining centers, capable of mass-producing interior components for premium vehicle brands such as Audi and Volkswagen. To address custom requirements for high-mix, low-volume production, we utilize coordinate measuring machines (CMM) and vision measuring systems for full-dimensional inspection, ensuring that dimensional accuracy and aesthetic consistency from mold development to batch delivery meet OEM standards.
